Study Notes

Overview

This article explores the anatomical aspects of the human body's sense organs, specifically focusing on the eyes, ears, skin, nose, and tongue. We delve deeper into the internal components such as the cornea, eardrum, dermis, taste buds, nasal cavity, hair follicles, papillae, olfactory nerve, epidermis, and retina.

Eyes

Cornea: Transparent protective layer that covers the eye's anterior portion.
Retina: Innermost layer of the eye containing photoreceptor cells (rods and cones) that convert light into neural signals.

Ears

Eardrum: Thin membrane separating the outer and middle ear, transmitting sound vibrations to the inner ear.

Nose

Nasal Cavity: Space within the nose where air is conditioned before entering the respiratory system.
Olfactory Nerve: Neural pathway connecting the olfactory receptors in the nasal cavity to the brain, allowing us to perceive different smells.

Skin

Epidermis: Outermost layer of skin providing barrier protection against external factors.
Dermis: Middle layer of skin containing connective tissues and providing mechanical support.
Papillae: Small projections on the skin's surface that increase sensation and touch sensitivity.

Tongue

Taste Buds: Clusters of sensory cells located on the tongue's surface, responsible for detecting different tastes (sweet, sour, salty, bitter, and umami).
